What did the slave ships transport in the last leg of the triangular trade path

The triangular trade was a commercial route that was established in the Atlantic Ocean from the seventeenth to the nineteenth centuries, so it can be considered a long-lasting historical phenomenon. Its denomination is due to the fact that, on the map, it drew a figure similar to a triangle, involving three continents.

Created by Portugal when it took over the Gulf of Guinea in the 15th century, it began with the departure of Western Europe (Portugal, France, England and the Netherlands, with the exception of Spain that since the promulgation of the laws of Burgos in 1512, banned the slave trade until the eighteenth century when, with the liberalization of port trade with the Americas of Carlos III, Spain joined the triangular trade) with manufactures or supplies of all kinds. It was re-scaled on the west coast of Africa, between the Senegal and Congo rivers, centered in the area generically known as Guinea, where some products (sometimes called quincalla: bells, mirrors, colored beads, low quality fabrics) could serve For the exchange. The product that was loaded there were black slaves, whose trade and supply, through continuous wars, was encouraged by local elites and merchants. The next scale was the islands of the West Indies or the American coast, where slaves and most European goods were sold, and colonial products (sugar, tobacco, cocoa) and precious metals were loaded back to Europe.

i also think he is correct. i believe they came to washington to protest their rights.

since most of current immigration into the u.s., both legal and illegal, is coming from latin america. it would be very difficult to imagine or rationalize a country my fellow citizens are trying desperately to flee into, would pose a threat to my prosperity or freedom. since the u.s. has a long history of intervention, but no record of permanent occupation, i would not feel oppression is the main objective.  

the largest free trade nation, along with the largest gdp in the world wanting to expand it's economic policy on us, and including us, could only be positive. the u.s. government has no interest in, or way of simply forcing american culture on us. and has no track record of it. other nations that adopted american social culture, or "americanization" did so voluntarily, mainly through the choice of allowing american businesses and u.s. citizens to come into their nations, as free operatives.
